Description

Die Erfindung betrifft ein Ventil, insbesondere Heizkörperventil, mit einem Gehäuse, das einen Einlaßanschluß und einen Auslaßanschluß aufweist, wobei im Strömungsweg zwischen diesen beiden Anschlüssen eine Absperreinrichtung mit einem Ventilelement und einer Ventilsitzanordnung angeordnet ist, wobei die Ventilsitzanordnung einen ersten Ventilsitz, der dem Einlaßanschluß zugeordnet ist, und einen zweiten Ventilsitz, der dem Auslaßanschluß zugeordnet ist, aufweist und das Ventilelement gleichzeitig mit beiden Ventilsitzen zusammenwirkt.The invention relates to a valve, in particular radiator valve, with a housing having an inlet port and an outlet port, wherein in Flow path between these two connections one Shut-off device with a valve element and a Valve seat assembly is arranged, wherein the valve seat assembly a first valve seat, the inlet port is assigned, and a second valve seat, which is associated with the outlet port, comprising and Valve element cooperates simultaneously with two valve seats.

Ein derartiges Ventil, das zur Steuerung von heißem Wasser in einem Heizsystem in privaten Wohnungen verwendet werden kann, ist aus EP 0 444 879 A1 bekannt. In diesem Ventil ist eine Membrane vorgesehen, die zwei Mündungen in einem Gehäuseunterteil überdeckt, nämlich eine Mündung, die mit einem Einlaß in Verbindung steht und einer Mündung, die mit einem Auslaß in Verbindung steht. Die Membrane wird durch die Kraft einer Druckfeder in Anlage an das untere Gehäuseteil gehalten und verschließt dementsprechend die beiden Kanäle. Die Membran ist zwischen dem Gehäuseunterteil und einem Gehäuseoberteil eingeklemmt und dichtet damit gleichzeitig die Verbindung zwischen dem Gehäuseunterteil und dem Gehäuseoberteil ab. Ein Elektromagnet ist vorgesehen, um die Membrane über einen Stößel gegen die Kraft der Rückstellfeder von den beiden Mündungen abzuheben.Such a valve, which is used to control hot Water used in a heating system in private apartments is known from EP 0 444 879 A1. In This valve is a membrane provided, the two Mouths covered in a lower housing part, namely an orifice communicating with an inlet and an orifice communicating with an outlet stands. The membrane is powered by the force of a compression spring held in contact with the lower housing part and accordingly closes the two channels. The membrane is between the lower housing part and an upper housing part clamped and sealed at the same time the connection between the lower housing part and the Housing top off. An electromagnet is provided around the diaphragm via a plunger against the force of Return spring from the two mouths.

Ein weiteres als Heizkörperventil ausgebildetes Ventil ist aus WO 99/22282 bekannt.Another designed as a radiator valve valve is known from WO 99/22282.

Heizkörperventile haben in der Regel eine vorgegebene Durchflußrichtung, die in manchen Fällen auf der Außenseite des Gehäuses mit einem Pfeil markiert ist. Oft ergibt sie sich auch nur aus einer Einbauanweisung, oder entsprechende Hinweise fehlen völlig. Diese Durchflußrichtung muß bei der Montage beachtet werden, um Störungen zu vermeiden, die sich vor allem durch unangenehme Geräusche bemerkbar machen. Wenn die Ventile "richtig" eingebaut werden, dann trifft das Wasser (oder eine andere Heizflüssigkeit), das durch den Einlaßanschluß einströmt, durch den Ventilsitz hindurch auf das Ventilelement. Wenn nun das Ventilelement auf den Ventilsitz zu bewegt wird, dann findet eine allmähliche Drosselung des durchströmenden Wassers statt. Bei dieser "korrekten" Betriebsweise ergeben sich normalerweise keine Probleme. Radiator valves usually have a predetermined Flow direction, which in some cases on the outside of the housing is marked with an arrow. Often if it results only from a fitting instruction, or corresponding information is missing completely. This flow direction must be observed during assembly to To avoid disturbances, which are mainly due to unpleasant Make noises noticeable. When the valves "properly" installed, then meets the water (or another heating fluid) through the inlet port flows through, through the valve seat on the valve element. If now the valve element on the valve seat is moved to, then finds a gradual Throttling of the flowing water instead. at This "correct" mode of operation normally results no problem.

Anders sieht es aus, wenn das Ventil falsch angeschlossen wird, d.h. die Speiseleitung eines Heizungssystems mit dem Auslaßanschluß verbunden wird. In diesem Fall strömt das Wasser über das Ventilelement zum Ventilsitz und von dort in den Einlaßanschluß. Wenn das Ventil schließt, wird das Ventilelement auf den Ventilsitz zu bewegt. Wenn der Spalt zwischen dem Ventilelement und dem Ventilsitz eine gewisse Größe unterschreitet, schließt das Ventilelement schlagartig, was einen ebenso plötzlichen Druckanstieg am Auslaßanschluß zur Folge hat. Dieser Druckanstieg äußert sich in einem Wasserschlag. Der Wasserschlag hat nicht nur unangenehme Geräusche zur Folge, sondern kann auch Beschädigungen im Leitungssystem hervorrufen. Dieser Wasserschlag kann aber auch durch einen anderen Impuls ausgelöst werden, beispielsweise durch ein anderes Ventil, das plötzlich schließt oder öffnet, eine Pumpe, die anläuft oder stoppt, oder anderes. Diese Ursachen, die noch nicht alle restlos geklärt sind, sind besonders kritisch dann, wenn das Ventil falsch montiert ist.It looks different if the valve is connected incorrectly is, i. the feed line of a heating system is connected to the outlet port. In this case the water flows through the valve element to the valve seat and from there into the inlet connection. When the valve closes, the valve element is on the valve seat to emotional. When the gap between the valve element and the valve seat falls below a certain size, closes the valve element abruptly, which is an equally sudden increase in pressure at the outlet connection result Has. This pressure increase manifests itself in a water hammer. The water hammer does not only have unpleasant noises As a result, but can also damage the Cause line system. This water stroke can but also be triggered by another impulse, for example through another valve that suddenly closes or opens, a pump that starts or stops stops, or else. These causes, not yet all are completely cleared, are particularly critical then, if the valve is mounted incorrectly.

In den letzten Jahren hat die Gefahr von Fehlmontagen von Heizkörperventilen zugenommen. Dies wird hauptsächlich auf zwei Ursachen zurückgeführt. Zum einen kann man nicht mehr beim gesamten Montagepersonal die notwendige Qualifikation voraussetzen. Zum anderen kann man gelegentlich in älteren Häusern oder Anlagen nicht mehr genau feststellen, welche Leitung zum Zufluß und welche zum Abfluß des Heizwassers verwendet wird, vor allem dann, wenn man vor einer Demontage versäumt hat, die Durchflußrichtung festzustellen. In recent years, the risk of incorrect assembly has increased from radiator valves. This is mainly attributed to two causes. For one thing you do not have the whole assembly staff anymore Require qualification. On the other hand one occasionally does not work in older homes or facilities determine more exactly which line to the inflow and which is used to drain the heating water before especially if you have failed to disassemble determine the flow direction.

Der Erfindung liegt die Aufgabe zugrunde, ein Ventil unabhängig von der Durchströmrichtung betreiben zu können.The invention is based on the object, a valve to operate independently of the flow direction.

Diese Aufgabe wird bei einem Ventil der eingangs genannten Art dadurch gelöst, daß die beiden Ventilsitze in einem Einsatz angeordnet sind und der Einsatz mit einem diagonal verlaufenden Dichtring gegenüber dem Gehäuse abgedichtet ist.This object is achieved with a valve of the aforementioned Art solved by the fact that the two valve seats are arranged in an insert and use with a diagonal sealing ring opposite the housing is sealed.

Damit stellt man unabhängig von der Montagerichtung sicher, daß das Ventilelement immer vom durchströmenden Wasser durch eine Öffnung, die von einem Ventilsitz begrenzt ist, angeströmt wird. Wenn das Ventilelement auf den Ventilsitz zu bewegt wird, ergibt sich immer eine allmähliche Drosselung des freien Strömungsquerschnitts. In keinem Fall wird bei einer derartigen Anordnung eine Situation auftreten, bei der das Ventilelement durch zuströmendes Heizungswasser auf den Ventilsitz herabgedrückt wird. Das Wasser strömt also immer gegen die Seite des Ventilelements, die mit der Ventilsitzanordnung zusammenwirkt, und zwar unabhängig davon, durch welchen Anschluß das Wasser einströmt. Hierbei ist es nicht erforderlich, daß das Ventilelement an beiden Ventilsitze exakt gleichzeitig zur Anlage kommt, obwohl eine zeitliche Übereinstimmung angestrebt werden sollte. Es reicht aus, wenn beide Ventilsitze durch das Ventilelement beaufschlagt werden, bevor sich in der Umgebung des Ventilelements ein Druck aufbauen kann, der das Ventilelement schlagartig auf den noch freien Ventilsitz drückt. Auch in einem derartigen Fall ist aber die Gefahr eines Wasserschlages außerordentlich gering, weil das zufließende Wasser durch die Drosselung am bereits geschlossenen Ventilsitz in ausreichendem Maße abgebremst worden ist. Der Ausdruck "geschlossener Ventilsitz" wird als Abkürzung für den Zustand verwendet, in dem das Ventilelement am Ventilsitz anliegt. Da die beiden Ventilsitze in einem Einsatz angeordnet sind, ergibt sich eine sehr einfache und kostengünstige Konstruktion, weil eine Bearbeitung des Gehäuses nur in einem relativ geringen Umfang erforderlich ist. Man muß das Gehäuse dahingehend bearbeiten, daß der Einsatz dichtend eingesetzt werden kann. Im übrigen kann das Gehäuse "leer" bleiben, weil sämtliche Führungsflächen und -wände für das Wasser im Einsatz ausgebildet werden können. Da der Einsatz mit einem diagonal verlaufenden Dichtring gegenüber dem Gehäuse abgedichtet ist, benötigt man nur einen Dichtring, um den Einsatz im Gehäuse abzudichten. Gleichzeitig ist aber die notwendige Trennung zwischen Einlaß und Auslaß gegeben, wenn das Ventil geschlossen ist.This ensures, regardless of the mounting direction, that the valve element always from the flowing through Water through an opening bounded by a valve seat is, is being streamed. When the valve element on the valve seat is moved, always results in a Gradual throttling of the free flow cross-section. In no case, in such an arrangement a situation occur where the valve element by inflowing heating water on the valve seat is pressed down. So the water always flows against the side of the valve element, with the Valve seat assembly cooperates, independently of which connection the water flows through. It is not necessary that the valve element at both valve seats exactly at the same time to the plant comes, although a temporal coincidence sought should be. It is sufficient if both valve seats be acted upon by the valve element before in the vicinity of the valve element, a pressure can build up, the valve element abruptly press the still free valve seat. Also in such a Case, but the danger of a water blow is extraordinary low, because the incoming water through the throttling at the already closed valve seat in has been slowed down sufficiently. The expression "closed valve seat" is an abbreviation for the Condition used in which the valve element on the valve seat is applied. Because the two valve seats in one use are arranged, results in a very simple and cost-effective construction, because a machining the housing required only to a relatively small extent is. You have to work the case to that the insert be used sealing can. Moreover, the housing can remain "empty" because all guide surfaces and walls for the water in the Insert can be trained. Since the use with a diagonal sealing ring opposite the housing is sealed, you only need a sealing ring, to seal the insert in the housing. simultaneously but is the necessary separation between intake and outlet when the valve is closed.

Hierbei ist bevorzugt, daß beide Ventilsitze in der gleichen Begrenzungswand einer Ventilkammer angeordnet sind, in der das Ventilelement senkrecht zu der Begrenzungswand bewegbar ist. Dies ist eine relativ einfache Ausbildung. Durch eine Bewegung des Ventilelements senkrecht zu der Begrenzungswand können beide Ventilsitze gleichzeitig beaufschlagt werden, d.h. die Öffnungen, die von den Ventilsitzen gebildet werden, können gleichzeitig geschlossen werden. Eine komplizierte Bewegungssteuerung des Ventilelements dahingehend, daß beide Ventilsitze gleichzeitig beaufschlagt werden, ist nicht erforderlich.It is preferred that both valve seats in the same boundary wall of a valve chamber arranged in which the valve element is perpendicular to the boundary wall is movable. This is a relatively simple one Education. By a movement of the valve element perpendicular to the boundary wall can both valve seats be applied simultaneously, i. the openings, which are formed by the valve seats can closed at the same time. A complicated one Motion control of the valve element to the effect that both valve seats are acted upon simultaneously is not mandatory.

Vorzugsweise ist der Einsatz aus einem Kunststoff gebildet. Das Gehäuse besteht normalerweise aus Metall. Die Verwendung eines Kunststoffs hat den Vorteil, daß der Kunststoff in der Regel etwas nachgiebiger ist als der Werkstoff des Gehäuses, so daß die Dichtigkeit leichter herzustellen ist, beispielsweise dadurch, daß der Kunststoffeinsatz in das Gehäuse eingepreßt wird. Kunststoff läßt sich darüber hinaus leicht bearbeiten und mit der notwendigen Genauigkeit formen.Preferably, the insert is formed of a plastic. The housing is usually made of metal. The use of a plastic has the advantage that The plastic is usually a bit more yielding than the material of the housing, so that the tightness is easier to produce, for example, in that the plastic insert is pressed into the housing. Plastic can also be easily edited and shape with the necessary accuracy.

Hierbei ist besonders bevorzugt, daß der Einsatz als Spritzgußteil ausgebildet ist. Spritzgießen ist ein relativ einfaches Verfahren, um Kunststoffteile zu formen.It is particularly preferred that the use as Injection molded part is formed. Injection molding is a relative simple process to form plastic parts.

Vorzugsweise umschließen die beiden Ventilsitze Öffnunggen, die gemeinsam an eine Kreisfläche angepaßt sind. Damit ist es möglich, ein Ventilelement zu verwenden, das ebenfalls eine Kreisflächenform aufweist. Man nutzt nun diese Kreisflächenform für möglichst große Öffnungen aus, damit das Ventil genügend Durchflußkapazität hat. Die gute Ausnutzung muß nicht bedeuten, daß die gesamte Fläche unter dem Ventilelement vollständig von den Öffnungen, die von den Ventilsitzen definiert werden, ausgenutzt wird. Es reicht aus, wenn die Öffnungen groß genug sind, um die gewünschte Ventilkapazität bereitzustellen.Preferably, the two valve seats enclose opening gene, which are adapted together to a circular area. This makes it possible to use a valve element which also has a circular surface shape. One uses now this circular surface shape for the largest possible openings out, so that the valve has enough flow capacity Has. The good exploitation does not have to mean that the entire area under the valve element completely from the openings defined by the valve seats, is exploited. It is enough if the openings are large enough to provide the desired valve capacity.

Hierbei ist besonders bevorzugt, daß die beiden Ventilsitze konzentrisch zueinander angeordnet sind. Damit läßt sich die Fläche unterhalb des Ventilelements am besten ausnutzen.It is particularly preferred that the two valve seats are arranged concentrically with each other. In order to can the area below the valve element on best exploit.

Bevorzugterweise ist eine Trennwand, die den inneren Ventilsitz bildet, an ihrer dem Ventilelement zugewandten Stirnseite abgerundet. Dies führt dazu, daß das Ventil ein verhältnismäßig niedriges Geräuschniveau hat. Normalerweise liegt die Rundung im Bereich von 0,75 bis 1 mm, und dieses Maß kann dann auch die Dicke der Trennwand definierten. Das Verhältnis der Fläche, die von der Trennwand umschlossen ist, zu der Fläche eines Ringkanals, der außen um die Trennwand herumgeführt ist, richtet sich nach den Kapazitätsanforderungen an das Ventil. Vorzugsweise sollten beide Flächen zumindest annähernd gleich sein.Preferably, a partition, which is the inner Valve seat forms, facing at its the valve element Rounded end. This causes the Valve a relatively low noise level Has. Normally, the rounding is in the range of 0.75 to 1 mm, and this measure can then also the thickness the partition defined. The ratio of area, which is enclosed by the partition, to the surface an annular channel, which led around the outside of the partition is, depends on the capacity requirements to the valve. Preferably both surfaces should be at least approximately equal.

Vorzugsweise weist das Ventilelement in einem Bereich, der mit dem äußeren Ventilsitz zusammenwirkt, eine Dichtlippe auf. Damit wird die Kraft, die zum vollständigen Schließen des Ventils erforderlich ist, klein gehalten. Man kann erreichen, daß die Ventilkammer abgedichtet wird, bevor der Spalt zwischen Ventilelement und Trennwand vollständig geschlossen ist. Dies ergibt eine hohe Zuverlässigkeit bei der Vermeidung eines Wasserschlags, da unabhängig von der Durchflußrichtung immer eine allmähliche Drosselung der durchströmenden Wassermenge erfolgt. Preferably, the valve element is in an area which cooperates with the outer valve seat, a Sealing lip on. This will be the power to complete Closing the valve is required, small held. It can be achieved that the valve chamber sealed before the gap between the valve element and partition is completely closed. This results high reliability in avoiding a water hammer, because regardless of the flow direction always a gradual throttling of the flowing through Amount of water takes place.

Die Bewegung des Ventilelements 6 wird dabei von einer nur schematisch dargestellten Betätigungseinrichtung 9, beispielsweise einen von einem Thermostatventilaufsatz gesteuerten Stößel, gesteuert. Aus Gründen der Übersicht sind Einzelheiten, wie Rückstellfedern oder ähnliches, nicht dargestellt.Between the inlet port and the outlet port 4th a shut-off device 5 is arranged, which is a valve element 6, which is movable in a valve chamber 7 is, in the direction of a double arrow. 8 The movement of the valve element 6 is thereby of a only schematically illustrated actuator 9, for example, one of a thermostatic valve top controlled ram, controlled. For the sake of clarity are details, such as return springs or the like, not shown.

Der Einlaßanschluß 3 ist über einen Kanal 10 und der Auslaßanschluß 4 ist über einen Kanal 11 mit der Ventilkammer 7 verbunden. Die jeweiligen Mündungen der Kanäle 10, 11 in die Ventilkammer 7 sind von Ventilsitzen 12, 13, umgeben, die hier nur schematisch dargestellt sind. Sie können jegliche bekannte Form aufweisen, beispielsweise ringförmige Wülste oder einfach Dichtflächen, die mit einer Stirnseite 14 des Ventilelements 6 dichtend zusammenwirken können.The inlet port 3 is via a channel 10 and the Outlet port 4 is connected via a channel 11 with the valve chamber 7 connected. The respective mouths of the channels 10, 11 in the valve chamber 7 are of valve seats 12, 13, surrounded, which are shown here only schematically are. They may be of any known form, for example annular beads or simply sealing surfaces, with an end face 14 of the valve element. 6 can cooperate sealingly.

Das Ventilelement 6 ist so groß, daß es beide Ventilsitze 12, 13 überdeckt. Dies hat mehrere Effekte zur Folge: Zum einen wird das Ventilelement 6 immer an seiner Stirnseite 14 angeströmt. Jegliche Schließbewegung des Ventilelements 6 erfolgt also gegen den Druck des zuströmenden Wassers. Zum anderen ergibt sich beim Schließen immer eine zunehmende Drosselung zwischen dem Ventilelement 6 und beiden Ventilsitzen 12, 13, so daß das durchströmende Wasser zuverlässig gedrosselt wird. Wenn dann das Ventilelement 6 an den beiden Ventilsitzen 12, 13 anliegt, dann ist das durchströmende Wasser allmählich abgebremst worden und zum Stillstand gekommen, so daß kein Druckstoß vorkommt, der schlagartig abgebaut werden muß.The valve element 6 is so large that there are both valve seats 12, 13 covered. This has several effects Result: First, the valve element 6 is always on his End face 14 flowed. Any closing movement the valve element 6 thus takes place against the pressure of the inflowing water. On the other hand arises at Always closing an increasing throttling between the Valve element 6 and two valve seats 12, 13, so that the water flowing through is reliably throttled. If then the valve element 6 at the two valve seats 12, 13 is applied, then the water flowing through gradually slowed down and stalled, so that no pressure surge occurs, the sudden must be reduced.

Fig. 1 zeigt auch einen vergrößerten Ausschnitt des Ventilelements und der Begrenzungswand der Ventilkammer 7, in der die Kanäle 10, 11 münden. Zusätzlich zu den Kanälen 10, 11 können weitere Kanäle (nicht dargestellt) vorgesehen sein, die mit dem Einlaßanschluß 3 bzw. mit dem Auslaßanschluß 4 in Verbindung stehen, so daß der Strömungsquerschnitt, der für die durchfließende Flüssigkeit zur Verfügung steht, vergrößert wird. Auch die anderen Kanäle sind an ihren Mündungen von Ventilsitzen umgeben, die nicht näher dargestellt sind und auch einfach durch die die Mündungen umgebenden Flachen gebildet sein können. Für das Ventilelement 6 können noch Führungsstifte 10a, 11a vorgesehen sein.Fig. 1 also shows an enlarged detail of Valve element and the boundary wall of the valve chamber 7, in which the channels 10, 11 open. In addition to the Channels 10, 11 may have additional channels (not shown) be provided with the inlet port. 3 or with the outlet port 4 in conjunction, so that the flow cross-section, for the flowing through Liquid is available, is increased. The other channels are also at their mouths Surrounded valve seats, which are not shown in detail and also simply by the mouths surrounding it Flat can be formed. For the valve element 6 can still be provided guide pins 10a, 11a.

Die Fig. 2 bis 4 zeigen abgewandelte Ausführungsformen, wobei das Ventil nach Fig. 2 für eine abgewinkelte Anordnung vorgesehen ist, während das Ventil nach Fig. 3 für eine gerade durchgehende Montage vorgesehen ist. Die Erläuterung erfolgt daher hauptsächlich anhand der Fig. 3, wobei gleiche Teile mit gleichen Bezugszeichen versehen sind.FIGS. 2 to 4 show modified embodiments, the valve of Fig. 2 for an angled arrangement is provided while the valve of FIG. 3 is intended for a straight through mounting. The explanation is therefore mainly based on the Fig. 3, wherein like parts with like reference numerals are provided.

Im Gehäuse 2 ist ein Einsatz 15 angeordnet, der als Spritzgußteil aus Kunststoff gebildet ist. Der Einsatz ist in einer Bohrung 16 angeordnet, die im vorliegenden Fall senkrecht zum Einlaßanschluß 3 verläuft. Andere Winkel sind möglich. Das Gehäuse 2 ist hier lediglich schematisch dargestellt. Natürlich weist das Gehäuse 2 mindestens eine Öffnung auf, durch die der Einsatz 15 in das Gehäuse 2 eingesetzt werden kann. Diese Öffnung kann durch einen Deckel verschlossen werden. Der Einsatz 15 kann auch am Deckel befestigt sein.In the housing 2, an insert 15 is arranged, as Injection molded part made of plastic is formed. The use is disposed in a bore 16 in the present Fall perpendicular to the inlet port 3 runs. Other Angles are possible. The housing 2 is here only shown schematically. Of course, the housing 2 at least one opening through which the insert 15 can be inserted into the housing 2. This opening can be closed by a lid. The use 15 may also be attached to the lid.

Der Einsatz 15 weist eine Trennwand 17 auf, die sich im Querschnitt über die gesamte Fläche des Einlaßanschlusses 3 erstreckt. An seinem Boden weist der Einsatz 15 einen Fuß 18 auf, der bei der Ausgestaltung nach Fig. 2 auf der Seite des Einlaßanschlusses 3 geschlossen ist, während er bei der Ausgestaltung nach Fig. 3 durchgehend geschlossen ist. Der Einsatz 15 weist ferner einen Kopf 19 auf. Im Kopf 19 sind eine erste Öffnung 20 und eine zweite Öffnung 21 angeordnet, die von einer Ringfläche 22 gemeinsam umschlossen werden, wobei die Ringfläche 22 mit dem Ventilelement 6 zusammenwirkt. Ferner ist ein auf die Trennwand 17 aufgesetzter Steg 23 vorgesehen, der ebenfalls mit dem Ventilelement 6 zusammenwirkt. Der Steg 23 und die Ringfläche 22 bilden zwei Ventilsitze, die die Öffnungen 20, 21 umgeben.The insert 15 has a partition wall 17 which extends in Cross section over the entire surface of the inlet port 3 extends. At its bottom, the insert 15 a foot 18, which in the embodiment of FIG. 2 is closed on the side of the inlet port 3, while in the embodiment of FIG. 3 continuously closed is. The insert 15 also has a Head 19 up. In the head 19 are a first opening 20 and a second opening 21 arranged from an annular surface 22 are enclosed together, with the annular surface 22 cooperates with the valve element 6. Further a patch 23 is provided on the partition wall 17 which also cooperates with the valve element 6. The web 23 and the annular surface 22 form two Valve seats surrounding the openings 20, 21.

Der Einsatz 15 weist auf seiner dem Einlaßanschluß 3 zugewandten Seite eine Öffnung 24 und auf der gegenüberliegenden Seite eine Öffnung 25 auf. Wie durch gestrichelte Pfeile 26 dargestellt, ist es dann, wenn das Ventilelement 6 vom Kopf 19 abgehoben ist, möglich, daß die Heizflüssigkeit durch die Öffnung 24 in den Einsatz 15, durch die Öffnung 20 in die Ventilkammer 7, durch die Öffnung 21 wieder in den Einsatz 15 eintritt und den Einsatz dann entweder durch die Öffnung 25 oder durch eine Öffnung 26 im Fuß 18 in dem Auslaßanschluß 4 übertritt. Falls das Ventil "falsch" montiert ist, ist der Strömungsweg umgekehrt. In beiden Fällen ist sichergestellt, daß das Ventilelement 6 von der "richtigen" Seite her angeströmt wird.The insert 15 has on its the inlet port. 3 facing side an opening 24 and on the opposite side Side an opening 25. As by dashed Arrows 26 shown, it is when the Valve element 6 is lifted from the head 19, possible that the heating fluid through the opening 24 in the insert 15, through the opening 20 in the valve chamber 7, through the opening 21 again enters the insert 15 and then use either through the opening 25 or through an opening 26 in the foot 18 in the outlet port 4th transgresses. If the valve is mounted "wrongly" is the flow path is reversed. In both cases it is ensured that the valve element 6 of the "right" Side is streamed.

Wenn das Ventil geschlossen wird, wird das Ventilelement 6 auf den Einsatz 15 abgesenkt, wodurch sich der Spalt zwischen dem Ventilelement 6 einerseits und dem Steg 23 bzw. der Ringfläche 22 andererseits allmählich verringert. Da in der Ventilkammer 7 kein zusätzlicher Druck aufgebaut wird, kann das Ventilelement 6 gesteuert bis zur Anlage an den Einsatz 15 bewegt werden.When the valve is closed, the valve element becomes 6 lowered onto the insert 15, causing the Gap between the valve element 6 on the one hand and the Web 23 and the annular surface 22 on the other hand gradually reduced. As in the valve chamber 7 no additional Pressure is built up, the valve element 6 can be controlled be moved to the plant to the application 15.

Der Einsatz 15 ist durch einen diagonal angeordneten Dichtring 27 gegenüber dem Gehäuse 2 abgedichtet. Dieser Dichtring 27 bewirkt eine zuverlässige Dichtung zwischen Einlaßanschluß 3 und Auslaßanschluß 4. Ein Flüssigkeitsstrom ist nur bei geöffnetem Ventilelement 6 möglich. Anstelle eines einzigen diagonal angeordneten Dichtrings können auch zwei Dichtringe verwendet werden.The insert 15 is arranged by a diagonal Sealing ring 27 sealed from the housing 2. This Seal 27 causes a reliable seal between inlet port 3 and outlet port 4. A Liquid flow is only with the valve element open 6 possible. Instead of a single diagonally arranged Sealing ring can also use two sealing rings become.

In der Ausführungsform nach den Fig. 2 bis 4 sind die einzelnen Öffnungen 20, 21, die von den als Ventilsitz dienenden Flächen 22, 23 umgrenzt.In the embodiment according to FIGS. 2 to 4 are the individual openings 20, 21, as the valve seat serving surfaces 22, 23 bounded.
